In-Tank Spargers

Mott in-tank spargers increase gas absorption by as much as 300% over traditional sparging technologies, resulting in faster throughput and less gas usage. Mott spargers can be used with virtually any gas or liquid to improve gas absorption in a variety of processes. Because porous metal provides thousands of flow paths, gas exits through the spargers in very small bubbles resulting in far better absorption than traditional sparging technology. Whether you’re looking for a single sparger or multiple sparger assemblies for a large tank, we’re here to fulfill your needs.

Sparging Overview

Mott's overview of sparging technology, configurations, and applications.

Sparging Design Guide

High surface area means fast, efficient mass transfer. The key to high-efficiency sparging is fine bubble propagation which provides maximum surface area for effective "mass transfer." Mott precision porous metal creates fine bubbles over a broad range of application requirements. This is Mott's Sparging Design Guide.
